2: Introduction | Have you ever wondered what causes a natural disaster? The four major natural disasters are tornadoes, hurricanes, volcanoes, and earthquakes. Scientists have made websites to give people information about natural disasters. These websites will give information on how to prepare for a natural disaster.
3: We got this F.E.M.A logo from F.E.M.A
4: Tornadoes | A tornado is formed when warm moist air rises and cold dry air falls in a violent storm called a super cell, thus making a tornado. Also air pressure falls making a funnel cloud drop to the ground, that usually that lasts for about six miles. Scientist use satellite images to detect super cells in the atmosphere. The scientists who use these satellite images are called meteorologists. The damage done by a tornado is measured on the Richter scale. | Did you know that Texas holds the world record for tornadoes with 120 a year? | WOW
5: A photo sent to natural geographic | Have you ever heard the expression it's raining cats and dogs? Well it has rained frogs and fish! A nearby tornado swept up house hold pets and they rained down the next day. | WOW
6: Earthquakes | An earthquake is formed when pressure in the ground between faults and plates build and release thus breaking rocks which causes the ground to quake. Scientist use seismographs to study the ground shaking. Earthquakes happen more frequently by faults that is why scientists use seismographs to detect where these faults are. There is really no way you can prevent an earthquake, but you can follow instructions that could help you stay alive.
8: Volcanoes | A volcano is caused by vents on the earth's surface which shoots molten rock, gasses, and ash. Scientists that study volcanoes are called volcanologists. During a volcano eruption you should fallow evacuation orders issued by the government. Scientists predict eruptions by using seismographs to detect earth's movement by a volcano. An estimate of 260,000 people have died by volcanoes over the past 300 years! | On November 13, 1985 Nevado del Ruiz, a rank 5 in the world volcano, erupted in Columbia killing 23,000 people. | Did you know that is a volcano hasn't erupted in 200 years it's officially dormant? | Did you know about 1,900 volcanoes are considered active? | WOW
9: This is Mt. Semu the highest volcano in Indonesia | Volcanic lightning at the Eyjafjallajkull volcano in Iceland in April 2010. | WOW | WOW | WOW | WOW
10: Hurricanes | Did you know that hurricanes rotate counter clockwise? Also did you know that 90% of all. hurricane deaths come from storm surges? Also, hurricanes can cause floods and landslides! A hurricane is formed when wind spirals 74 mph over the south Atlantic, Caribbean, Gulf of Mexico, and east pacific oceans. Scientist detects hurricanes by satellite images of a swirling looking cloud. Also to help protect you from a hurricane secure the windows, board doors, get up high and also turn off electronics.

12: Conclusion | The four major natural disasters are tornadoes, hurricanes, volcanoes, and earthquakes. Scientists have made websites to give people information about natural disasters. The four major natural disasters are tornadoes, hurricanes, volcanoes, and earthquakes. Scientists have made websites to give people information about natural disasters. There are many more natural disasters out there. So go to websites like F.E.M.A. to get information on them.
13: This photo was taken in Texas they named it the mother ship.
14: Prep page | Tornadoes: To prepare for a tornado duck and cover under a sturdy piece of furniture and cover your head and neck with your arms Volcanoes: To prepare for a volcano pack basic supplies such as water, food, flashlight, fresh batteries, and a battery powered radio. Then follow evacuation orders if given. Hurricanes: Duck and cover, like a tornado, turn off electronics, and beware of flooding. Move to higher ground if it starts to flood. earthquakes: To prepare for an earthquake make an emergency supply pack filled with the basic supplies and cover your head and neck with your arms.
